Description

Technical Field

[0001] The invention relates to the technical field of metal roof bearing systems, in particular to a high-bearing metal roof. Background Art

[0002] Metal roofing is a roofing material that combines a structural layer and a waterproof layer into one. There are many types of metal sheets, including galvanized sheet, galvanized sheet, aluminum alloy sheet, aluminum-magnesium alloy sheet, titanium alloy sheet, copper sheet, and stainless steel sheet. The surface of the sheet can be painted.

[0003] The overall structure of the metal roof has waterproof and drainage functions. Regardless of the shape of the building, the joints can be completely sealed. There are no nail holes in the entire roof, which allows the roof to expand and contract freely when the temperature changes, avoiding temperature stress, and eliminates the hidden dangers of leakage caused by the system screw fixing method.

[0004] However, the metal roofing systems on the market are mainly lightweight and low-load-bearing structures, which can only be used for simple waterproofing and supporting performance, with weak bearing capacity and a relatively single and limited applicable environment. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved high-load-bearing metal roof is provided to solve the problem that the metal roof systems on the market are mainly lightweight and low-load-bearing structures, can only be applied to simple waterproofing and supporting performance, have weak bearing capacity, and are applicable to a relatively single and limited environment.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a high-load-bearing metal roof, including stainless steel purlins installed on the roof, multiple stainless steel panels are provided at the upper ends of the stainless steel purlins, and stainless steel cover plates are fixed to the upper ends of the stainless steel panels at the connection ends. The connection ends on both sides of the stainless steel panels are fixed by continuous sealing welding. The two ends of the stainless steel panels have upwardly bent lateral assembly folds, and the lateral assembly folds and the connection ends of the stainless steel panels have inclined bending sections for preventing thermal expansion and contraction. The lower ends of both sides of the stainless steel cover plates are fixed to the outer connection ends of the lateral assembly folds by spot welding and full-length sealant.

[0007] The thickness of the stainless steel purlin is 1.0mm-1.5mm, the thickness of the stainless steel panel is 1.0mm-1.5mm, and the thickness of the stainless steel cover is 1.0mm-1.5mm.

[0008] The stainless steel purlin is an "X"-shaped structure, and a plurality of strip-shaped assembly holes with built-in self-tapping and self-rotating nails are opened inside the folded edges on both sides of the stainless steel purlin. The stainless steel purlin is fixed to the top of the roof through the self-tapping and self-rotating nails inside the strip-shaped assembly holes.

[0009] The bending angle of the oblique bending section is 45°.

[0010] The beneficial effects of the present invention are:

[0011] (1) The high-load-bearing metal roof of the present invention uses an "X"-shaped stainless steel purlin to support the connection end of the stainless steel panel, which greatly improves the bottom load-bearing capacity of the stainless steel panel, thereby greatly improving the application range of the metal roof;

[0012] (2) It is fixed at the upper end of the stainless steel panel assembly position. The form can be changed according to the customer or demand. It not only has a decorative effect but also has the function of preventing rain leakage and protecting the steel frame.

[0013] (3) The 45° bend section is used at the connection ends of the stainless steel panel and the lateral assembly folding edges on both sides, which not only ensures the assembly, but also offsets the deformation caused by thermal expansion and contraction due to heat, thereby improving the sealing and stability of the assembly;

[0014] (4) Setting the welding surface of the side assembly fold inside the stainless steel cover can greatly improve the sealing of the connection end and the firmness of the welding end. By using spot welding and full-length sealant to fix the connection at both ends of the stainless steel cover, it is convenient for later disassembly and inspection.

[0022] Figure 1 、 Figure 2 and Figure 3 A high-load-bearing metal roof shown includes a stainless steel purlin 1 installed on the roof, with two stainless steel panels 2 provided at the upper end of the stainless steel purlin 1. The upper end of the stainless steel purlin 1 is located at the connection end of the stainless steel panel 2 and is fixed with a stainless steel cover plate 3. The connection ends on both sides of the stainless steel panel 2 are fixed by continuous sealing welding. The two ends of the stainless steel panel 2 have upwardly bent lateral assembly flanges 4. The lateral assembly flanges 4 and the connection ends of the stainless steel panel 2 have inclined bending sections 5 for preventing thermal expansion and contraction. The lower ends of both sides of the stainless steel cover plate 3 are fixed to the outer connection ends of the lateral assembly flanges 4 by spot welding and full-length sealant.

[0023] Furthermore, in order to improve the bearing capacity, the thickness of the stainless steel purlin 1 is 1.5 mm, the thickness of the stainless steel panel 2 is 1.5 mm, and the thickness of the stainless steel cover plate 3 is 1.5 mm.

[0024] Furthermore, in order to facilitate installation, the stainless steel purlin 1 has an "J"-shaped structure, and can also be set to various forms such as "Z" shape, L-angle steel shape, etc. according to needs. Six strip-shaped assembly through holes with built-in self-tapping and self-rotating nails 7 are opened inside the folded edges on both sides of the stainless steel purlin 1. The stainless steel purlin 1 is fixed to the top of the roof through the self-tapping and self-rotating nails 7 inside the strip-shaped assembly through holes 6.

[0025] Furthermore, in order to offset the deformation caused by thermal expansion and contraction, the bending angle of the oblique bending section 5 is 45°.

[0026] like Figure 4 The first embodiment shown is as follows: first, the two ends of the stainless steel purlin 1 are fixed to the top of the roof by self-tapping and self-rotating nails 7, and then the lateral assembly flanges 4 at both ends of the stainless steel panel 2 are placed on the upper end of the stainless steel purlin 1, and then the adjacent lateral assembly flanges 4 are welded to each other and fixed, and then the stainless steel cover plate 3 is put on the upper end of the lateral assembly flange 4.

[0027] like Figure 5 The second embodiment shown: in order to further improve the bending resistance, an upwardly protruding integrated structural support frame 8 is provided at the top of the stainless steel cover plate 3, wherein the height of the support frame 8 is 8.64 mm, the angle between the support frame 8 and the internal connection end of the stainless steel cover plate 3 is 111.5°, and the width of the stainless steel cover plate 3 is 43 mm. An internal assembly strip 9 is fixed on the inner side surface of the stainless steel cover plate 3, and a horizontal support limit plate 10 is installed inside the stainless steel cover plate 3 above the lateral assembly fold 4 through the internal assembly strip 9.

[0029] Furthermore, in order to facilitate loading and unloading, a lateral mounting bolt 11 for installing the internal assembly strip 9 is welded and fixed on the inner side of the stainless steel cover plate 3. A lateral mounting through hole matching the lateral mounting bolt 11 is opened inside the internal assembly strip 9. The internal assembly strip 9 is fixedly connected to the inner side of the stainless steel cover plate 3 by being inserted into the lateral mounting bolt 11 through the lateral mounting through hole.

[0030] Furthermore, in order to facilitate assembly, the inner assembly strip 9 has an inner limiting groove on its inner wall away from the fixed assembly end, and the inner side wall of the transverse support limiting plate 10 has an arc-shaped limiting protrusion 12 that matches the inner limiting groove.

[0031] A high-load-bearing metal roof of the present invention adopts a cross-shaped stainless steel purlin 1 to support the connection end of the stainless steel panel 2, greatly improving the bottom bearing capacity of the stainless steel panel 2, so that it can greatly improve the applicability of the metal roof; the stainless steel panel 2 is sleeved and fixed at the upper end of the assembly position, and the form can be changed according to the customer or demand, which not only has a decorative effect but also has the function of preventing rain leakage and protecting the steel frame; an oblique bending section 5 with an angle of 45° is adopted at the connection end of the two sides of the stainless steel panel 2 and the lateral assembly folding edge 4, which not only ensures the assembly, but also offsets the deformation caused by thermal expansion and contraction caused by heat, thereby improving the assembly sealing and stability; the welding surface of the lateral assembly folding edge 4 is set inside the stainless steel cover plate 3, which can greatly improve the sealing of the connection end and at the same time improve the firmness of the welding end, and the stainless steel cover plate 3 is fixed at both ends with spot welding and full-length sealant, thereby facilitating later disassembly and inspection.
